From basic calculations and problem generators to interactive three-dimensional graphics, Mathematica is a tremendous tool for teaching and learning mathematics. I have been using Mathematica in various ways with my students for over a decade. In this talk I will present examples of different strategies for how Mathematica can be incorporated into a classroom setting along with experiences showing students and other teachers how to use Mathematica. Also, I will share Mathematica notebooks created by my high school and middle school students that illustrate their interests in math, science, art, music, and more!
